NAME
     scalar - Process scalars easily.


  Functions
     netsnmp_mib_handler * netsnmp_get_scalar_handler (void)
         Creates a scalar handler calling netsnmp_create_handler
         with a handler name defaulted to 'scalar' and access
         method, netsnmp_scalar_helper_handler.
     int netsnmp_register_scalar (netsnmp_handler_registration
         *reginfo)
         This function registers a scalar helper handler.
     int netsnmp_register_read_only_scalar
         (netsnmp_handler_registration *reginfo)
         This function registers a read only scalar helper
         handler.
     int netsnmp_scalar_helper_handler (netsnmp_mib_handler
         *handler, netsnmp_handler_registration *reginfo,

         netsnmp_request_info

Detailed Description
     Process scalars easily.

Function Documentation
  netsnmp_mib_handler* netsnmp_get_scalar_handler (void)
     Creates a scalar handler calling netsnmp_create_handler with
     a handler name defaulted to 'scalar' and access method,
     netsnmp_scalar_helper_handler.

     Returns:
         Returns a pointer to a netsnmp_mib_handler struct which
         contains the handler's name and the access method

net-snmp                                                scalar(3)



     This function is very similar to netsnmp_register_scalar the
     only addition is that the 'read_only' handler is injected
     into the handler chain prior to injecting the serialize
     handler and registering reginfo.

     Parameters:
         reginfo a handler registration structure which could get
         created using netsnmp_create_handler_registration. Used
         to register a read only scalar helper handler.

     Returns:
         MIB_REGISTERED_OK is returned if the registration was a
         success. Failures are MIB_REGISTRATION_FAILURE and
         MIB_DUPLICATE_REGISTRATION.

  int netsnmp_register_scalar (netsnmp_handler_registration *
     reginfo)
     This function registers a scalar helper handler.

     The registered OID, reginfo->rootoid, space is extended for
     the instance subid using realloc() but the reginfo-
     >rootoid_len length is not extended just yet. .This function
     subsequently injects the instance, scalar, and serialize
     helper handlers before actually registering reginfo.

     Each handler is injected/pushed to the top of the handler
     chain list and will be processed last in first out, LIFO.

     Parameters:
         reginfo a handler registration structure which could get
         created using netsnmp_create_handler_registration. Used
         to register a scalar helper handler.

     Returns:
         MIB_REGISTERED_OK is returned if the registration was a
         success. Failures are MIB_REGISTRATION_FAILURE and
         MIB_DUPLICATE_REGISTRATION.
